Question
I have kitchen cabinets that were originally finished with a lacquer product approx 15 years ago.  The finish has not held up well around moisture, as it clouds.  I would like to apply a spar type product probably spar urethane but am concerned about applying it over lacquer.  I spoke to Minwax and Sikkens and they both told me that their products are not recommended over lacquer.  Are they being overly cautious and can I apply urethane over lacquer?  If not, what can I use for refinishing that is not lacquer?

Thanks

Marc

Hi Marc
Nice to hear from you.
This clouding you mention is my concern.
Does it come and go or is it there permanently?
And I would never apply a spar varnish on cupboards..even bare wood ones.
So if the cloud comes and goes, and is not permanent, there is nothing wrong with some experimenting.
I don't feel the companies are overcautious but short of a total refinish theres not much else to do but "try something".
So..take a door off. Try this on the back side which hopefully will have most of the finish the front has.
First use a degreaser type product to be sure there is no dirt or grease present.
Then lightly sand or better still use medium grade steel wool and rub the surface to slightly deglaze it.
Next rub on with rag a light coat of wipe on poly (yep Minwax LOL).
Just a little area.
On another small area, wipe on with a rag a coat of low luster tung oil (I use Circa brand).
When dry, replace the door and watch the results a few days.
Nothing ventured nothing gained LOL.
I might add here that I have applied tung oil over lacquer too many times to mention so don't let the naysayers tell you differently.
Keep me posted.
